Motorised Dish Part 2
Made an app which provides continuous movement of the motors whilst a button is pressed, by implementing OnTouchListener.

Motorised dish
After weeks of fiddling about with servos, I think the motorised dish is finally built.
I was trying to use 2 Tower Pro MG995 servos which are high-torque and really cheap, but they are terrible. In the end I spent a little more and am now using 2 Towardpro MG996R servos, which are even higher torque, and perfect for what I need. The tilt and pan brackets were ordered from China.
The video shows a simple demo sketch I've written, just to test the strength of the servos. The ADK generates random values (within defined limits) for the azimuth and elevation angle, and then writes them to the servos. Impressively, the whole thing is powered by a single USB port. I have ordered a separate power supply for the motors, but it may not be necessary.
The next step is to finish writing an app capable of controlling the dishes movements (I have started, but was held up by those shocking MG995s, AVOID!)
